У меня возникли проблемы с моделью просмотра, которая постоянно возвращает свойства null после публикации. Ниже мой код (это может быть проблема синтаксиса или два вызова класс или свойство такое же имя, как я видел в других постах, но я не мог видеть любой такой вопрос в коде):Добавлено ViewModel return null properties
VIEW МОДЕЛЬ:
public class ProductItem
{
public int ProductID { get; set; }
public string Code { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public string LongDescription { get; set; }
public int SupplierID { get; set; }
public string Dimensions { get; set; }
public double Price { get; set; }
public bool On_Sale { get; set; }
public double DiscountedPrice { get; set; }
public string Thumbnail { get; set; }
public string LargeImage { get; set; }
public string LargeImage2 { get; set; }
public string LargeImage3 { get; set; }
public string CrossRef { get; set; }
public byte Available { get; set; }
public double Weight { get; set; }
public byte Important { get; set; }
public virtual ICollection<ProductCategory> ProductCategories { get; set; }
// this is required on the page to allow products to be marked for deletion
public bool IsForDelete { get; set; }
}
public class ProductListViewModel
{
public IEnumerable<ProductItem> ProductItems { get; set; }
public IEnumerable<Category> CategoryItems { get; set; }
}
CONTROLLER:
public ActionResult ProductList()
{
var productList = new ProductListViewModel();
productList.ProductItems = productRepository.GetProductsWithDeleteOption().ToList();
productList.CategoryItems = categoryRepository.GetCategories().ToList();
return View(productList);
}
[HttpPost]
public ActionResult ProductList(ProductListViewModel productViewModel, FormCollection formCollection, string submit)
{
if (ModelState.IsValid)
{
// Check for submit action
if (submit == "Change Sort")
{
if (formCollection["Sortby"] == "ProductID")
{
OrderBy(productViewModel, formCollection, "m.ProductID");
}
else if (formCollection["Sortby"] == "Code")
{
OrderBy(productViewModel, formCollection, "m.Code");
}
else if (formCollection["Sortby"] == "Name")
{
OrderBy(productViewModel, formCollection, "m.Name");
}
else if (formCollection["Sortby"] == "Price")
{
OrderBy(productViewModel, formCollection, "m.Price");
}
}
else if (submit == "Delete all selected")
{
}
else if (submit == "Update All")
{
}
else if (submit == "Restrict Display")
{

}
return View(productViewModel);

В пост действия, productViewMo del аргумент имеет свойства ProductItems и CategoryItems как null.
